Generic communication interface between the wireless board (mote) and the sensor board. Any kind of sensor board can be connected to the mote using this specification given it provides a SPI peripheral, one input pin with interrupt capability and one digital output. The sensor board must implement a special register set from which all required information can be retrieved. Protocol: http://is.gd/wuQorh Github: http://is.gd/ySj1L9
